2 Claims. 1 This invention relates to Iimprovementsjin hose clasps and similar devices and isacontinua'tion of my copending application Seria1lio. 681;026 filed July 2, 1946, now abandoned.

An object of the invention is to provide an improved hose clasp consisting of a body memher having alatera'l-ly disposed head adjacent one end thereof and which has swingably connected thereto a keeper or gripping member adapted to swing ,into closing engagement with the head and closed with a snap-over action. The improved construction is characterized by the fact that the head and-sides of the keeper taper or converge upwardly toward the swingableconnection between the parts and that the swingable connection permits of a small limited sliding movement of the keeper relatively to the body to permit of a weclging action 'to "take place between the substantially rigidheadand thekeeper to grip hose .or asimilar fabricitherebetween. It

is also characterized by the fact that the keeper provides opposed slightly resilient arm-s engageable with the lower ends-of the head with'sna'p= over action in looking or unlockingthe-clasp.

The improved clasp is highly advantageous in that the body "is formed of a substantially rigid material and the clasp is closed by merely inserting the body beneath "the fabric and swinging the keeper into closing and gripping position by snapping it over the head. The design is such that when the material or fabric of the hose *is subjected to extreme tensile stresses, the clasp will automatically open and release the material before the hose will be-torn thereby.

iVIany users of -clasps "of this character 'have occasion to ield or double the hose at the location where it is engaged by the clasp. The improved clasp is so -'desig-ned that it may efiectively clasp the hose "regardless of whether a single layer is positioned over the head-of the body or the hose is double and positioned between the head andthekeeper.

Another object of the invention is "to provide a hose clasp which is so designed that it will effectively gripan'd retain'against slipping hard or synthetic hose fabrics such asny'lon or rayon. These fabrics frequently will'slip or pull through a conventional :type of hose clasp even though the clasp remains-completelyclosed.

Still another object of the invention is to provide an improved hose'clasp which is'so designed that it will close with snap action without involving slip back? In "the conventional type of hose clasp inasmuch as the body or part that carries'thehead'oftheclasp is flexible the'kee'per or loop ;is drawn downwardly over the head and "then released upwardly with the result that the elastic or tape to which the clasp is fastened is frequently looser at the time that the clasp is closed than at the time when the keeper is being positioned over the head. This slip back may be'entirely avoided in a clasp embodying the present invention.

With the foregoing and other objects in View, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

'Figure l is a front view in elevation of the improved clasp illustrating it in applied position;

Fig. 2 is an edge view in elevation of the clasp;

Fig. 3 ,is a vertical section taken substantially upon the lined-:3 upon 'Fig. 1; and

Fig. 4 is a sectional view taken substantially upon the line ll upon Fig. '1.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the -improved clasp consists of an elongated body "It preferably formed of a substantially rigid material such as for example a synthetic resin plastic which may be readily molded to the desired shape. This body presents'asubstantially fiat rearor under-surface and on the forward side thereof adjacent its lower end thereis alatera'lly or forwardly disposedhead l I. 'The'top of thebody is substantially'th'ickened as at 12 and has on its ends elongated "recesses 13. Adjacent-one or both of these recesses there are small communicating'grooves "M. The head presents sides [-5 and 16 which converge upwardly and which are recessed or grooved as indicated at H. These grooves extend across the sides of the head 'at a slight angle to the length of thebody being somewhat-more forwardly disposed at the upper ends of the sides than at the lower endsof the sides.

The lower-ends of thesegrooves merge smoothly with a rebated or undercut portion l8 at the bottom of the head so that the body of the head presents a rounded'snap over edge 19. A-keeper is provided which is formed of sheet metal or similar material, this "keeper consisting of two opposed sides ill and *2! integrally connected by a bottom 22 that is-disposed some distance below the bottom edge It oi'the'head. The sides 26 and 2| are so shapedas to converge upwardly adjacent the upwardly converging sides It and Not the head. Above the :bottom 22 the sides have integral therewith opposed arms 23 and 2t.

3 These arms possess a slight degree of resiliency and are adapted to pass over the edge I9 with a snap-over action in engaging the keeper with the head. The upper ends of the arms 20 and 2| are provided with opposed pinions or trunnions 25 and 26 that enter the elongated recesses l3. These pinions may be inserted into the recesses by passing them through the connecting grooves [4. The upper ends of the sides 20 and 2| are preferably braced against spreading by means of an integral brace or case 21. The side 20 has integral therewith an arm 28 which extends across the top of the keeper and has its end slightly spaced from the upper end of the side 2 I providing an entering throat 29 for a loop or elastic or tape indicated at 30. The underside of this arm preferably presents a convex edge 3| so that the loop of elastic or tape will tend to remain distributed across the bottom edge of the arm.

As will be observedfrom Fig, 2, the keeper is so shaped that it is bowed outwardly from its swingable connection provided by the pintles or trunnions 25 and 26 and then inclined downwardly and rearwardly adjacent the sides l5 and I6 of the head. Finally it is bent rearwardly to a point approximately flush with the fiat rear or underside of the body so that the bottom 22 of the keeper up to the approximate location of th resilient arms 23 and 24 is disposed approximately in the plane of the underside of the body I0.

In use the body I!) is positioned beneath the hose H which may be either of single or double thickness and the keeper is swung downwardly and rearwardly causing the arms 23 and 24 to snap over the edge [9. During this snap-over action the pintles or trunnions 25 and 26 are crowded to the extreme upper ends of the elongated recesses l3. When the clasp is then released and tension is applied to the hose H the hose tends to be drawn downwardly against the upwardly convergent sides l5 and I6 and to draw the keeper downwardly with it so that its upwardly convergent sides will depress the fabric of the hose into the grooves I"! on the sides of the head. This serves to adequately fasten the hose to the clasp and retain it in fastened condition for all ordinary stresses. However, it will be found that a clasp constructed as above described will automatically open when the hose H is subjected to extreme tension to thus release the hose automatically prior to its tearing.

As the arms 23 and 24 are relatively short and stubby the resiliency of these arms is such that it will be retained for an indefinite period enabling the keeper to always properly snap over the edge [9 regardless of the extent to which the clasp is used. In this way continued use does not weaken the resiliency of the arms and allow the clasp to accidentally open. Upon opening the clasp it is merely necessary to depress the head through the opening that is bounded on three sides by the arms 23 and 24 and the sides 20 and 2l.

It will be observed that when the hose H is drawn or pulled downwardly, it is effective to urge the body and the head in a rearward direction through the keeper. This causes the tops of the grooves IT to press the fabric against the upwardly convergent sides. The folding of the fabric of the hose from the engagement between the tops of the grooves and the upwardly convergent sides of the keeper down across the forward face of the head and rearwardly above the 4 opposed arms will effectively look even hard or synthetic fabrics such as nylon or rayon against slipping.

As the clasp will close with snap action without materially altering or changing the elevation of the body or of the keeper, slip bac is effectively avoided.

It will be appreciated from the above-described construction that the arts of the clasp can be very easily engaged and disengaged and that they can be very easily and economically manufactured and assembled. In assembling the parts of the clasp it is merely necessary to pass the trunnions or pintles 25 and 26 through th grooves [4 or if only one groove is employed one pintle 26 may be positioned in its recess l3 and the other pintle passed through the groove into its recess. When the pintles have been positioned in their recesses the parts of the clasp will not ordinarily separate during usage.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claims.
